TECHNICAL FIELD

The present invention relates to a fungicidal composition mainly for agricultural and horticultural use.

BACKGROUND ART

Various agricultural and horticultural fungicides have been known, but there are a great variety of diseases to be controlled and it is difficult to specify the kind of the disease in practice and control the disease by choosing a fungicide suitable for the disease. In addition, it is necessary to cope with the appearance of fungi which have acquired tolerance to specific agents and the occurrence of novel diseases due to the change of the mode of agriculture. For these reasons and the like, there is desired a fungicidal composition having a high activity and a wide anti-microbial spectrum.

The present invention provides a fungicidal composition which has a high activity and a wide antimicrobial spectrum and is markedly effective also against diseases caused by plant pathogenic fungi which have acquired tolerance to certain fungicides.

Then, the young seedling was inoculated with a suspension of spores of apple scab fungus by spraying. After the inoculation, the young seedling was allowed to stand in the dark at 15° C. and a high humidity for 4 days and then grown under illumination for 15 days, after which the infection rates investigated.

Test Example 14

Each of plastic pots was filled with sandy loam and planted with a grape (Berry A) plant, and a wettable powder of test agents prepared according to Formulation Example 47 was diluted to a predetermined concentration with water and sprayed on the plant so as to adhere to the surfaces of leaves of the plant, after the plant put out a fourth leaf. After air-drying, the surfaces of the leaves were inoculated with a suspension of spores (2×10⁵ spores/ml) of grape powdery mildew fungus (Uncinula necator) by spraying. After the inoculation, the plant was grown at 24° C. for 3 weeks and then the infection rate (%) was investigated.

The results are shown in Table 14.

Test Example 15

A tomato plant (cultivar: Ponterosa) was planted in each pot and was sprayed with a sufficient volume of a dilution with a predetermined concentration of a wettable powder obtained according to Formulation Example 53, after the plant put out a third leaf. After air-drying of the spray mix, the surfaces of the leaves were inoculated with a suspension of spores (5×104 spores/ml) of tomato late blight fungus (Phytophthora infestans) by spraying. After the inoculation, the plant was grown at 24° C. for 1 week and then the infection rate (%) was investigated.

Each of plastic pots was filled with sandy loam and planted with a grape (Berry A) plant, and a wettable powder of test agents prepared according to Formulation Example 53 was diluted to a predetermined concentration and sprayed on the plant so as to adhere to the surfaces of leaves of the plant, after the plant put out a fourth leaf. After air-drying, the surfaces of the leaves were inoculated with a suspension of spores (2×105 spores/ml) of grape powdery mildew fungus (Uncinula necator) by spraying. After the inoculation, the plant was grown at 24° C. for 3 weeks and then the infection rate (%) was investigated.
